Description

pressure_relief
Pressure relief

This is a 12-ton hydraulic "bottle" jack mounted to a steel frame so it can be used as a press. The pressure relief valve is located on the press base. This machine is generally used for bending sheets and bars, and it usually has a 4" wide right-angle bending tool and die set mounted. The opening in the frame is 16" wide.

Use for:

  • Bending steel sheets and bars up to 1/8" thick

Do not use for:

  • High-carbon or Hardened steel
  • Round or square stock

Safety Hazards

Warning Safety glasses Eye protection required!


  • Workpiece can unexpectedly snap
  • Pinching injuries
  • Cuts/scrapes from sharp edges and burrs

Tooling

dead_blow
Removing the tool with a "dead-blow" hammer.
bender_longit
Longitudinal bending tool.
bender_transv
Transverse bending tool.

The bending tool is press-fit onto the ram below the bottle jack. It can be positioned at any angle, but the two most useful orientations are shown here: longitudinal and transverse.

To remove the tool, hit it with a "dead-blow" hammer with a soft head until it lossens up and comes off. Reposition, and press it onto the ram using the press.
